BACKGROUND AND AIMS: Current treatment for genotype (GT) 2 or 3 hepatitis C virus infection is pegylated interferon and ribavirin (RBV) 800 mg/d for 24 weeks. This meta-analysis was carried out to assess whether the treatment duration can be reduced in patients with rapid virologic response (RVR) METHODS: Literature was searched for studies comparing short-term (12 to 16 wk) and 24 weeks treatment in GT 2 or 3 with RVR.RESULTS: Six studies (n=2434) were included and data on end-of-treatment response (ETR), sustained virologic response (SVR), and relapse rates (RR) were obtained. Pooled odds ratio (95% CI) for SVR and RR were 0.54 (0.35-0.85; P=0.008) and 3.12 (1.99-4.91; P<0.00001) favoring 24 weeks of treatment. Reducing treatment duration to 12 to 16 weeks and retreating relapses for 24 weeks was cost-effective.CONCLUSIONS: Reducing treatment duration to 12 to 16 weeks for GT 2 or 3 HCV patients with RVR is associated with a lower SVR and a higher RR. Advantages of short-term treatment include better patient compliance, lower rate of adverse effects, and cost. Short-term treatment may be an option for patients unable to tolerate treatment. Further studies are needed to identify factors predicting relapse with short-term treatment in GT 2 or 3 patients with RVR.
